This story happened early last week, but I just ran into it on TUAW. Fantastic!

iPhone developer Joseph Riquelme (AKA, Joey Trombone) took the money he made from his popular iOS video editing app, Videoshop, and put it to good use.

He gave his parents this note, letting them know he was paying off their mortgage.

Here’s the video of Joe giving his parents the note. Nicely done, Joe.
